Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle transfer loading / unloading mechanism of an elevator type multi-level parking device.

2. Description of the Related Art In recent years, elevator type multi-level parking devices have become popular for the purpose of speeding up, noise reduction, and cost reduction of tower-type multi-level parking devices, but there is still a problem to be solved in this system. .
That is, the method of placing an in-vehicle pallet on the elevator and storing the car together with the pallet in the designated floor is to return the empty pallet for the previously-delivered car to the designated floor where the previously-delivered car was stored when the garages are continuous. Requires extra operating time. Also, in the case where the elevator has a retractable shelf push-out mechanism or a transfer arm mechanism, the retractable or transfer operation of the retractable shelf can be started only after the elevator reaches the designated floor, and the retractable shelf The elevator cannot leave the designated floor and move to the next operation until the push-back or the transfer operation is completed. Therefore, it is difficult to realize the shortest entry / exit time, and it is difficult to move the power supply and control cable together with the elevator. Further, in the case where each storage rack is provided with a power source for transverse reversal, there is a problem in that price rises and the control system becomes complicated, and maintenance is difficult to avoid. On the other hand, in recent years, due to the development of various sensors and computers, etc., means for procuring control systems such as operation sequence, position and speed of mechanical systems on a daily basis have been distributed. The problem lies in a vehicle transfer loading / unloading mechanism that realizes cost reduction and simplification of maintenance while minimizing the loading / unloading time.

The present invention aims to solve the above-mentioned problems.

Means for Solving the Problems The present invention has a plurality of parking shelves arranged vertically in multiple stages in the storage chambers on the left and right or in the front and rear of the elevating room that is operated to elevate by being guided by the guide rails provided at the four corners as described above. The storage shelves can be traversed from the storage room to the elevator room, from the elevator room to the storage room, and the vehicle can be delivered by combing the elevator forks and the storage shelves in the elevator room. In the multi-story parking apparatus, the traverse mechanism of the plurality of storage shelves is, in principle, provided with one moving wheel drive motor installed in a building, and a main driving wheel that is provided for each parking floor and is rotated through a chain by the moving wheel drive motor. , A sub driving wheel which is provided on the same level as each of the main driving wheels in a straight line and which respectively mounts and supports storage shelves, and a rotation of the main driving wheel which is arranged behind the guide rail is selected as the sub driving wheel. It is characterized by comprising a multiple clutch and a chain for transmitting the electric power, and an actuator for operating the multiple clutch.

Action According to the above, when the storage rack on either the left or right side or the front or rear side of the designated floor is traversed, the actuator on the designated floor operates at the same time as the drive wheel drive motor starts forward rotation, and the compound clutch on that floor is moved to either the left or right side. The auxiliary drive wheel is turned on to either one or one of the front and rear auxiliary drive wheels to rotate the auxiliary drive wheel in the forward direction, whereby the storage rack supported by the auxiliary drive wheel traverses and stops at a predetermined position in the elevator chamber. When the vehicle is delivered, the drive wheel drive motor starts rotating in the reverse direction, the drive wheels and auxiliary drive wheels rotate in reverse, the storage shelves in the lift chamber are returned to the storage room, the drive wheel drive motor stops, and the actuator turns off the double clutch. Then, the traverse / reverse operation of the storage rack is completed. In this way, in principle, all the storage shelves can be selectively traversed and traversed by one moving wheel drive motor, and at the same time, the elevator is lowered and the storage shelves are traversed at the same time during storage. In addition, the elevator can be raised and the storage shelves can be traversed at the same time when the vehicle is unloaded, so that the loading and unloading time can be shortened and the parking efficiency can be improved.

It is configured integrally with the projecting elevator fork 9, and the vehicle can be placed with the front, rear, left, and right wheels on the elevator fork 9.

The vertical beam 5 is loosely fitted and guided by the guide rail 2, and the length of the vertical beam 5 is determined in consideration of the guide function, strength, and vehicle transfer operation with a storage shelf to be described later.
It is appropriate to set the length to about 0.5m. Further, the horizontal beam 8 is offset and fixed inward from the lower end of the vertical beam 5 so as not to interfere with a storage rack traverse mechanism such as a main driving wheel 6 and a free wheel 7 which will be described later.

In the left and right storage chambers B of the elevating chamber A, storage shelves 28 for parking in which a plurality of shelf forks 29 combing with the elevator forks 9 of the elevator 33 are provided on the left and right are arranged in a multi-tiered manner.

The storage shelf 28 is mounted and supported so that the front and rear grooves can be horizontally traversed by fitting the auxiliary drive wheel 16 and the idler wheel 27 attached to the horizontal beam 32 of the building.

A main driving wheel 6 and a free driving wheel 7 are attached to the center portion of the building horizontal beam 32 in the left-right direction (inside the elevator chamber A) so as to be aligned with the left and right auxiliary driving wheels 16 and the free driving wheel 27.
By rotating one of the left and right auxiliary wheels 16, either the left or right storage rack 28 can be traversed in the same plane from the storage chamber B into the lift chamber A, or from the lift chamber A into the storage chamber B. It has become.

The traverse mechanism of the storage shelf 28 includes a single driving wheel drive motor 10 mounted at the center of the upper part of the building, and a shaft 11 and a sprocket 12 for transmitting the rotation of the driving wheel drive motor 10 to the shaft 15 of the main driving wheel 6 on each floor. , 13 and the chain 14 and the shaft 15 of the driving wheel 6
And a compound clutch 25 (which may be any compound clutch such as a mechanical type, an electromagnetic type, a hydraulic type, a pneumatic type, etc.) provided on the vehicle, and the rotation of the shaft 15 of the main driving wheel 6 depending on the operation of the compound clutch 25. Sprockets 17, 18, 21, 22 and chains 19, 20 selectively transmitting to one of the auxiliary wheels 16, an electromagnetic solenoid or hydraulic cylinder for actuating the multiple clutch 25,
It is composed of an actuator 26 such as a pneumatic cylinder.

Of the traverse mechanism of the above storage rack, sprockets 17,18,2
1,22, the chains 19,20 hanging on them, the double clutch 25, and the actuator 26 are provided behind the guide rail 2 that guides the elevator, so that the traverse mechanism does not interfere with the elevation of the elevator 33 at all. There is nothing to do.

It should be noted that, as shown in the illustrated embodiment, the driving wheel drive motor 10 is, as a general rule, one unit for traversing storage shelves on a plurality of floors.
When the building is high and the number of floors of the storage shelves 28 is large, the number of floors is divided into several blocks, and each block is provided with a drive wheel drive motor for each one before and after the elevator room A. The main driving wheel 6 on the floor may be driven by the chain 14. Even in this case, the number of driving wheel drive motors is 3 to 4 when divided into 2 blocks, and 5 to 6 when divided into 3 blocks. Further, as shown by the phantom line in FIG. 3, the shafts 23, 23, 24, 24 of the front and rear auxiliary driving wheels 16 are constituted by one shaft 23 ', 24' passing through in the front-rear direction, respectively. If the two auxiliary wheels 16 on the front and the rear are integrally rotated by the rotation of the shafts 23 ', 24', the sprocket 17, 18, 21, 22, the chain 19, 20, the multiple clutch 25 and the actuator on either side of the front and rear can be formed. 26 can be omitted.

Reference numeral 30 denotes a boarding stand of the vehicle. The boarding stand 30 is provided with a plurality of notches for combing with the elevator forks 9 of the elevator 33 on the left and right edges as shown in FIG. It is fixed at the bottom, that is, the entry floor (usually the first floor). The lifting motor 31 described above drives four chains 1 by itself (see FIG. 2).

 The storage operation in the above will be described below.

When entering the garage, ensure that the four wheels are correctly placed on the forks 9 of the elevator 33 that is stopped at the same level on the entry platform 30 that is installed at the same level as the floor of the entry floor, as shown in FIG. Get in a car. By giving necessary instructions to the control system, such as warehousing, designated floor and left / right, the elevator motor 31 is first activated, and the elevator chain 1 is moved up the elevator 33 by the elevator chain 1 and then rises a little further, and the vertical beam 5 When almost the center of the vertical dimension (about 0.5 m) coincides with the position of the storage shelf 28 on the designated floor for storage, the lift stops and immediately the double clutch 25 on the designated floor for storage, and the sprocket 17 for the right storage.
In the case of the left-side storage, the actuator 26 is operated so as to mesh with the sprocket 18, and the driving wheel drive motor 10 drives the main driving wheel 6 and the auxiliary driving wheel 16 so that the designated storage shelf 28 traverses inside the elevating chamber A. The drive wheel drive motor 10 is controlled so that the storage shelf 28 stops at the center of the lift chamber A. When the storage shelves 28 are stopped, the elevator 33 immediately begins to descend and the shelves fork 29
Hand over the car and return to the first floor without stopping.
On the other hand, the storage shelves 28 receive the automobile and immediately after the elevator passes downward, the driving wheel drive motor 10 reverses to return to the storage position, the driving wheel drive motor 10 stops, and the multiple clutch 25 returns to the neutral position to complete the warehousing.

Of the above-described warehousing operations, the elevator lowering operation after the delivery of the vehicle and the horizontal return operation of the storage rack 28 can be mostly advanced at the same time.

Upon delivery, by giving necessary instructions to the control system such as delivery, designated floor, left and right, etc., the double clutch 25 is engaged by the actuator 26 on the designated floor with either the left or right sprocket as specified. Drive wheel drive motor 10 is started and designated main drive wheel 6 and auxiliary drive wheel 16
28 is driven so as to traverse into the lift chamber A. The elevator motor 31 is also started at the same time, but the elevator 33 is vertically crossed with the designated storage shelf 28 in the ascending direction at the same timing as the designated storage shelf 28 stops traversing at the center position of the elevator room A, and the shelf fork is raised. After receiving the car above 29 onto the elevator fork 9, it still rises and stops until the position of the storage rack 28 matches the center of the vertical dimension of the vertical beam 5, and immediately the storage rack 28 is driven by a wheel drive motor. The reverse rotation of 10 returns to the front storage position and stops, the double clutch 25 returns to the neutral position, the elevator immediately descends and stops to the first floor, and the leaving operation is completed. In this state, the car can be started.

Among the above-mentioned shipping operations, most of the traversing operation of the storage shelf 28 into the elevating room A and the ascending operation of the elevator 33 can be simultaneously advanced.

Elevator 33 and designated storage shelves in the above loading and unloading operations
The operation sequence of 28 is shown in FIGS. 12 and 13, respectively. That is, at the time of warehousing, the descent of the elevator 33 after the delivery of the vehicle from (d) to (e) of FIG. 12 and the horizontal return of the storage shelf 28 are simultaneously proceeding, and at the time of warehousing, (a) of FIG. From (1) to (2), the raising of the elevator 33 and the traverse of the storage shelves 28 before the delivery of the vehicle are proceeding at the same time.

As described above, according to the mechanism according to the present invention, the total number of operations of the elevator and the storage shelf is 4 operations for each loading and unloading, which is one operation as compared with the conventional elevator having the storage shelf drawer push-back mechanism. In addition, the number of movements is one less than that of other conventional mechanisms that store together with pallets, and there is no need to return empty pallets during continuous warehousing, which minimizes the number of movements, that is, the storage time. Can contribute.

Further, in still another conventional parking apparatus provided with a traverse power source for each storage rack, a large number of traverse motors at least as many as the storable number of cars are required. Depending on the case, all the storage shelves can be traversed by several traversing motors, so that simplification of control, cost reduction, simplification of maintenance, etc. can be achieved.

Next, a second embodiment of the present invention will be described with reference to FIGS. 7 to 11.

The second embodiment shown in FIGS. 7 to 11 is an elevator.
The storage room B is arranged before and after the elevating room A in which the 33 moves up and down.
In comparison with the first embodiment, the transverse movement of the storage shelves 28 arranged in the storage chamber B in the upper and lower stages is a horizontal movement in the first embodiment, whereas a horizontal movement is in the front-back direction. All the other configurations and operations are the same as those of the first embodiment except for the differences, and the same reference numerals as those in the first embodiment represent the same parts.

In the second embodiment, the opening width of the parking device is 1/2 or less than that of the first embodiment, and one of the two front-surface open-space vehicles which is legally obliged to install is one of the areas. Because a considerable area can be used as a storage room on the second floor and above,
It has the advantage of further improving land use efficiency.
